New working version is up, just in time for the last few minutes of Make It Loud.

do you think you can make this functional for long tunes? it would start to get a little big after a 10-15 notes.
very good idea, and i hope you good luck.
it would still be cool playing just short melodies.

Originally it was a 100 mm ID with 15 notes, but I worried that due to the large volume on the inside that it would be difficult if not impossible for a person to blow enough air to make sound. Most flutes do not have an expansion, except maybe a slight taper, like a recorder. I planned on combining it with a hand powered fan that would be geared to provide both rotational movement (sequence) and air flow, but that was proving too complicated for a project that is just started. In the future I will experiment with large diameter models for more notes.

Great idea, i hope you get it working. I made a few PVC whistles, and also a few tapered bore metal ones, and i much prefer the metal bodied tapered bore whistle. They are easier to tune in my view, and the tuning between the lower and higher octaves are closer than with the parallel bore PVC pipe. When it comes to the time taken in making the whistles, the metal body takes a lot longer, along with a custom sanded and fitted wood fipple.
Good luck on your project though, i really hope you get it working well.

Thanks. If you could take a look at the fipple I designed and give me any feedback I would appreciate it. I went on google image searches, none of which have dimensions.

Sadly i do not have access to a 3D printer, so i can not try this print. The fipples i made were just cut on a band saw, and then sanded to fit using either a disk sander or a drum-sanding piece on the drill-press, and then repeated fitting till i am happy. The trick is to get the correct size of the airway over the fipple block, and then also the gap between the "cutting edge" of the airway and the end of the fipple. This is rather crucial, as it affects the ease with which the whistle breaks over from the low octave into the high octave.
This website, http://www.ggwhistles.com/howto/ has all that i know about whistle making, and the rest is all self taught, like how to make a tapered bore body from what some would call scrap metal. ( I used coffee tins, and paint tins for a good few and got some really good results.)
The site i mentioned gives you good tips on the width and length of the fipple and the airways, the rest was just me tinkering around with mostly handtools ( and a wood-lathe) to make a mandrell for the body of the whistle.
Sorry i can not be of more assistance.

That is actually the blog I mentioned I was using. Nothing left to do but print and test. Thanks for the input.

This is, in my opinion, just brilliant.

Thanks. Let's hope it works.
